A well-lubricated cut results in a smoother finish, reducing the need for secondary finishing operations. How Cutting Oil Works as a Coolant Cutting oil functions as an effective coolant by absorbing the heat generated during the drilling process and transferring it away from the tool.
How Cutting Oil Additives Prevent Welding During Metal Drilling
Selecting the Right Formulation Not all cutting oils are created equal, and selecting the correct one depends on the base metal being drilled. Best Practices for Application.
This adhesion creates a built-up edge, which ruins the geometry of the bit and leads to vibrations and poor hole finish. When a drill bit rotates and applies pressure, the kinetic energy is converted into thermal energy through friction.
How Additives Prevent Welding in Metal Drilling
Modern cutting oils contain specific additives that prevent this welding process from occurring. Preventing Workpiece Adhesion A specific and damaging issue when drilling metal is the tendency for small particles of the workpiece to weld onto the cutting edge of the drill.
